In this paper, the interactions between a large informed trader (IT, for short) and a high-frequency trader (HFT, for short) who can anticipate the former's incoming order are studied in an extended Kyle's model. Equilibria under various specific situations are discussed. We find that, in...

Suppose that consumers incur fixed shopping costs and choose stores according to advertised discounts. Then, the extent to which a store will discount advertised items should increase with the profit from other regularly-priced items. Bookstores customarily advertise discounts on bestsellers....

We address the question of designing dynamic menus to sell experience goods. A dynamic menu consists of a set of price-quantity pairs in each period. The quality of the product is initially unknown, and more information is generated through experimentation. The amount of information in the...

In this paper, we study a new channel to explain firms' price setting behavior. We propose that uncertainty about factor prices has a positive effect on markups. We show theoretically that firms with higher shares of inputs with volatile prices set higher markups. We use the Bartik shift-share...

How are a firm's size and market power related to one another? Combining micro-data about producers and consumers, we document that while firms mainly grow by selling to more customers, their markups are only associated with their average sales per customer. To study the macroeconomic...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing in its productivity. Variation in...

Retailers typically sell many different products from the same manufacturer at the same price. I consider retailer-based explanations for this uniform pricing puzzle, estimating the counterfactual profits that would be lost by a retailer switching from a non-uniform to a uniform pricing regime...
